neat.
Did you know the tobacco industry has attempted a "smokeless" cigarette twice before?
You can look at the links but to sum it up they had a carbon heating element at the tip and pretty much passed hot air through a nicotine capsule.
I have smoked the Eclipse and it tasted a bit like smoking a burning cabbage might taste...
Anyway it's interesting stuff. Here are links and you can explore from there.
Premier Cigarettes.
Eclipse cigarettes.
Smoking one was weird, you couldn't feel anything when you inhaled but you could exhale a HUGE cloud of steam.
EDIT: the marketing around these products is especially interesting as they were billed as "safe" cigarettes.
